Map of the Western Balkan region with triangles corresponding to the regions from where blood samples were collected.
The sample of Bosnia and Herzegovina consisted of subsamples of three main ethnic groups: Bosniacs (Sarajevo and Zavidovici), Bosnian Croats (Central Bosnia - Zepce and Maglaj; South Bosnia and Herzegovina - Mostar, Grude, Livno, Capljina), Bosnian Serbs (Doboj and Banjaluka region); Croatia (mainland, Zagreb region), Serbia (Belgrade region), Montenegro (Podgorica), Kosovo (Pristina and Prizren) and Macedonia (Skopje).

ADMIXTURE analysis of autosomal SNPs of the Western Balkan region in a global context on the resolution level of 7 assumed ancestral populations (See Table S1 for population data).
Figure 3.
Principal component (PC) analysis of the variation of autosomal SNPs in Western Balkan populations in Eurasian context (PC1 versus PC2; see Table S1 for population data).
Figure 4.
A: FST-distances based on the variation of autosomal SNPs. A: FST-distances of Western Balkans populations in a global context; B: Region-wise FST-distances of the studied populations. FST-values are from 0,03 (dark blue) to 0,00005 (dark brown).

Network of 29 populations constructed with the Neighbor-net approach from FST distances based on the variation of autosomal SNPs.
Western Balkan populations are indicated with violet color.
Figure 6.
TreeMix analysis of Western Balkan and surrounding populations (see Table S1 for population data).
TreeMix graph represents the model of 10 gene-flow events within the sample. A. The population tree with gene-flow (migration) events. The scalebar specifies the weight of a migration, precise value of it is shown on the migration edges; B. Residuals plot; C. Ultrametric tree.
Figure 7.
Average number of ibd segments per pair shared between Muslim Western Balkan populations (A – Bosniacs; B - Kosovars) and Middle Eastern (Saudis, Iranians, Syrians, Turks, Palestinians) and other non-Muslim Western Balkan populations (Bosnian Croats and Serbs, Croatians, Macedonians, Serbians, Montenegrins).
